I do appreciate what he wast trying to do; but I am in need of dire help here and don't need to be talked to like I'm an idiot.

You should forget the pinched wire theory as it is not the issue. Without us seeing what you did, it is a crap shoot for us to diag. Please listen to these guys as they are chock full of info and we always start at basics. I would start all over again, read the posts and follow our train of thought before going off on a tangent.

If 2 other people tell you that something is possible and you don't buy it. So what difference does it make if we tell you it is too? Would you accept by majority?
You don't even want to understand the basics of diagnostics so how is it possible for us to help you?
What we want to do is to get to the bottom of the prroblem and help you solve it but you must cooperate with us and give us as much information as possible. We ask questions and tell you to do specific things so that we can understand what could be the cause and rectify the problem.
If you want a staright answer as to yes otr no, ok here it is.
It is possible for a wire to be pinched. Is that what you want?

Nobody is treating you like an idiot-you just best listen and when you do, you learn like I do in here every single day dealing with attitudes and complicated car repair issues for 6yrs-You get my drift-Remember you're up against high tech professionals here-we're not backyards or partschangers we have credentials to substantiate it-Get with the program or go somewhere else and seek help-BTW there others way ahead of you that needs help too- be patient we'll get to you as time permits

I did check the fuses; that is not the problem. Next suggestion please?

Backtrack-go back and reopen the intake manifold to me it was nothing wrong with it in the very beginning-now you have created other problems- start here and keep us posted-

Let us start with the basics. I am only interested in information that would help us solve this problem.
Since there are a few problems, which are probably related to a certain extent, we have to start with something from among them.
For the low idling, check for vacuum leakage.
What was the reason for replacing the manifold?
Is the replacment manifold of the same type as previous?
Was the trrottle body rerplaced together with the maifold or was the original part reused? Was gasket replaced with the correct type and installed correctly?

Btw, which engine do you have?
Happy Father's day to all : )

I have checked for vacuum leaks & fixed 4 of them. The reason the manifold was replaced was that I was trying to replace the thermostat & in the process broke off a bolt in the manifold & drilled to far causing a HUGE hole in it. The replacement is the exact same; the gaskets came from O Reilly's. As far as the throttle body, that has not been replaced. Did not know I gad to replace that. The only issue I had was my manifold; nothing with the throttle body. And thank you for being patient with me. I have been working on this car for two weeks & just am extremely frustrated. O yeah, the engine is the 3.8 V6. And, on Monday, I did take the upper plenum back off & look and still same issue. I am almost scared to take it ALL apart again. I almost messed up quite a bit the first time. I was kinda hoping those issues would be over. Not only that; It's kinda a P.I.T.A!

No, the throttle body need not be replaced. But since it was out, you should have cleaned. While working on it, transferring it to the intake manifold, you could have dislodged some dirt which in turn would result in air restriction and this would cause idling problem.
Get a can of carb spray and open the throttle plate. Spray into the barrel and allow to soak for a while. If there are a lot of gumb, use a toothbrush to brush it clean.
Try starting to see if there are any changes. It might take some cranking time as the carb cleaner would cause some sort of flooding, too rich for combustion.
